A new compact and achromatic Michelson-type interferometer with a variable path difference is presented. This {open_quotes}fringe-counting sigmameter{close_quotes} allows to measure optical wavelength ratios between two radiations emitted by stabilized lasers. Maintained in vacuum, this apparatus can determine wavelength/frequency laser radiation from 0,36 {mu}m to 1,5 {mu}m with a relative accuracy of 5.10{sup -9}, with the use of a reference stabilized He-Ne laser.
